Application Bled November 9, 1905. Serial No. 286,601.

To all whom t may concern,.-

Be it known that I, HENRY AUGUSTUS VEAZIE, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Vaporizers, of which the following is 'a specification.

My invention pertains to devices for vapo-` rizing insecticides, disinfectants, and other solutions; and it contemplates the provision of a vaporizer constructed with a view of discharging insect-destroying orr other vapor into a closed room, and one embodying a nozzle having a vapor-conduit and a conduit arranged to receive condensed solution from the vapor-conduit and return such solution to the retort, this with a view of economizing in the use of the solution.

Other advantageous features peculiar to my invention will be fully understood from the following description and claims when the saine are considered in connection with the accompanying drawings, forming part of this specification, in which- Figure 1 is a view, partly in vertical section and partly in elevation, of the vaporizer constituting the present and preferred embodiment of my invention. Fig. 2 is a crosssection of the vaporizer-nozzle, taken in the plane indicated by the line 2 2 of Fig. l. Fig. 3 is an enlarged longitudinal section of said nozzle. Fig. 4 is an enlarged section taken through the longitudinal center of a modified nozzle, hereinafter referred to in detail.

Referring by letter to the said drawings, and more particularly to Figs. l to 3 thereof, A is the base of my novel vaporizer. The said base comprises a stand A, having upright sockets A2 and also having screws A3, bearing in the walls of said sockets, and up# right bars A4, adjustably held by the screws A3 in the sockets A2, whereby the base is adjustable as to height.

B is a heater, which is preferably in the form of a lamp, as illustrated, and B is a support and holder for the heater, which support and holder is provided with an arm B2, adjustablyfixed by a set-screw B5 on one of the uprights A4 of the base, this in order that the heater may be conveniently raised and lowered to increase and diminish the heating of the retort, presently described.

C is a casing fiXedly connected to the uprights A4 of the base and having lateral openings adjacent to its upper end for the escape hood D disposed above said openings and adapted to deflect such products downwardly.

E is a retort arranged in the casing and above the lamp, and F F are connections interposed between the casing and the retort and serving to hold the latter in theformer in such manner that the heated gases and other products of combustion from the lamp are free to pass upwardly between the casing and the retort and close to the latter, so as to assure proper heating thereof. The retortE may be ofany construction compatible with the purose of my invention, though I prefer to provide it with afilling-tube a, normally closed by a cap b, and also with an upwardly-extending nipple c, on which a brass ring c is brazed or otherwise fastened'.

is a drip-cup arranged on the hood D and interposed between said hood and the ring c.

G is a handle by which the vaporizer may be readily moved from place to place. The said handle is in the form. of a bail connected at its ends to the upper portion of the casing C and is preferably provided with a central ring d to hold it in an upright position, as shown.

F2 is a short threaded tube-section, between which and the ring c there is preferably a ground joint.

H is an upright tube resting in the ring d of handle G and on section F2 and having an annulus c, of non-conducting material, on its upper portion, whereby it may be conveniently handled when hot.

l is athreaded union detachably connecting the tube H to thesection F2, so as to permit of a longer tube being substituted for said tube H when necessary, and J is an angular tube having a lower vertical arm j", telescopically arranged in the tube H, and an upper inclined arm g, and also having an annulus h, of non-conducting material, on the latter, whereby it may be conveniently handled when hot.

K is a nozzle constructed in accordance with my invention. This nozzle comprises a base k, detachably connected by a bayonetjoint or other means to the upper end of the tube J, a vapor-conduit Z, open at its opposite ends, and a return-conduit m for condense solution disposed below the conduit Z and open at its inner end, so as to discharge into the tube J, but closed at its outer end. The said return-conduit m is connected with the conduit l, so as to receive condensed solution of products of combustion and also having a therefrom, and the said connection is prefer- IOO IIO

- a considerable portion of the solution is ably eected through a longitudinal slot p, extending the greater part of the length of the conduits, as shown in Figs. 2 and 3.

The discharge end of the vapor-conduit Z is preferably led or cut away, as indicated by Z, so as to increase the area of the discharge and afford a free vent for the fumes or vapors.

In lieu of the nozzle K the nozzle K Fig. 4, may be employed. This nozzle K is similar in construction to the nozzle K, except that it has apertures p between its conduits instead of a slot p.

In the practical use of my novel vaporizer the same is arranged on the floor outside the apartment to be disinfected, and the nozzle K is passed through the keyhole of a door, the knob-spindle opening in the door, or any other opening and into the said apartment. In this connection I desire to state that the nozzle K may be of the shape of a keyhole or any other shape in cross-section, according to the shape of the opening through which it is to be introduced, without involving departure from the scope of my invention. Before 0r after the introduction of the nozzle K into the apartment to be disinfected the retort E is charged withthe insecticide or other solution that it is desired to use, and the lamp B is lighted. With this done it will be observed that the vapor given off by the heated solution in the retort will pass through the tubes H and J and the conduit lof the nozzle K and into the apartment to be disinfected. It will also be observed that such of the vapor as is condensed in the portion of the conduit Z at the opposite side of the door with reference to the retort E will pass in the form of solution through the opening p into the conduit m and down the said conduit and the upper arm g of the tube J, which are inclined, as shown, to the retort E. In this way waste of revented, which is an important desideratlpim.

In order to accommodate the vaporizer to the height of the keyhole or other opening through which the nozzle K is to be introduced, a longer tube may be substituted for the tube I-I, if necessary, and the tube J is adj usted vertically in the tube which receives it.

In addition to the advantages hereinbefore ascribed to my novel vaporizer it will be seen that the same is quite as simple and inexpensive as the ordinary vaporizer and that it embodies no delicate parts such as are likely to get out of order after a short period of use.

Having described my invention, what I claim, and desire to.secure by Letters Patent, is-

1. The combination in a vaporizer, of a retort, and an inclined nozzle connected with the retort and comprising a vapor-conduit open at its opposite ends, and a return-conduit for fluid of condensation arranged below and connected with the vapor-conduit so as to 6 5 and comprising a vapor-conduit open at its 7o Vopposite ends, and a return-conduit for Huid of condensation arranged below and con-` nected with the vapor-conduit so as to receive therefrom and open at its rear end and closed at its forward end.

3. A nozzle for the purpose described comprising a vapor-conduit open at its opposite ends, and a return-conduit for :duid of condensation arranged below and connected with the vapor-conduit so as to receive therefrom and open at its rear end and closed at its forward end.

4. The combination in a vaporizer, of a retort, a tube connected with and extending upwardly from the retort, a tube having a lower arm telescopically arranged in the firstmentioned tube and also having an upper inclined arm, and a nozzle carried by the inclined arm ofthe second-mentioned tube, and comprising a vapor-conduit open at its opposite ends, and a return-conduit for fluid of condensation arranged below and connected with the vapor-conduit so as to receive therefrom and open at its rear end and closed at its forward end.

5. A nozzle comprising a vapor-conduit open at its opposite ends, a return-conduit for fluid of condensation arranged below the vapor-conduit and open at its rear end and closed at its forward end, and one or more openings intermediate the two conduits.

6. A nozzle comprising a vapor-conduit open at its opposite ends and having its discharge end beveled to increase the area of the discharge, a return-conduit for Huid of condensation arranged below the vapor-conduit and open at its rear end and closed at its forward end, and one or more openings intermediate the two conduits.

7. In a vaporizer, the combination of a casing having lateral apertures adjacent to its upper end, a hood closing the upper end of the casing and disposed over said apertures, and a retort arranged in the casing and having a nipple at its upper end extending through the hood.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HENRY AUGUSTUS VEAZIE.
